Biss announced through a video on Twitter that Wallace will replace Chicago Ald. Carlos Ramirez-Rosa as the candidate for Lieutenant Governor. Earlier this week, Biss dropped Ramirez-Rosa from the ticket over differing views on relations with Israel.

Biss called Wallace "the kind of person who inspired me to run for governor in the first place -- not one of the rich and powerful but an ordinary person just trying to get by."

In the video, Wallace said programs that she and Biss fought for include "childcare assistance, a $15 minimum wage, expanding healthcare, and we fought to make millionaires pay their fair share."

Wallace was appointed to the Illinois House in July 2014 to replace former State Rep. Chuck Jefferson, whom she served as chief of staff. She was elected to a full term in November 2016.

Wallace received a Ph.D. in Educational Psychology from Northern Illinois University and has a background in mental health counseling.
